Module 12 Summary

What this module established

A bar must name the set, the judge, a zero-tolerance metric and the operational bounds - one made entirely of rates permits every failure at some frequency. Evaluate each dimension against its own bar and let the weakest decide.

Carry forward

• Report latency at p50, p95 and p99, and state which rates are by design. A refusal rate matching your eval set is healthy.
• Add a tested column to the failure-mode table. A page of unverified mitigations reads as better coverage than it is.
• The report's output is a decision and a set of gates. A reliability report that never blocks a release is a report nobody is running.

Before moving on

You have finished when your report reaches a verdict against bars set beforehand, and proposes gates specific enough for someone else to run without asking you a question.
